Real-World Testing: Putting Corning Falcon Round-Bottom Tubes, Disposable, Polypropylene, 352018 14 Ml Tubes, Case of 1000 to the Test

First Use Experience

My initial testing ground for the Corning Falcon Round-Bottom Tubes was a multi-day water quality assessment in the Cascade Mountains. The tubes were used to collect stream water samples at various elevations, ranging from near freezing alpine streams to warmer, sediment-laden lower elevation sites. I subjected the tubes to real-world conditions, carrying them in a backpack through dense brush, exposing them to rain and temperature fluctuations.

The tubes performed admirably in terms of durability and containment. Despite being jostled around in my pack, none of the tubes cracked or leaked, even when filled with sediment-rich water. Their smooth, round bottoms made them easy to insert into makeshift racks constructed from fallen branches, and the polypropylene material proved to be surprisingly resistant to scratches and dents. However, the lack of caps forced me to improvise closures using parafilm, adding an extra step to the collection process and increasing the risk of contamination.

The absence of caps also made handling more cumbersome. Without a secure lid, I had to be extra cautious to avoid spills, especially when navigating steep terrain. While the tubes themselves performed as expected, the missing caps significantly impacted the overall usability and convenience of the product.

Extended Use & Reliability

After several weeks of intermittent field use, the Corning Falcon Round-Bottom Tubes have proven to be relatively robust and reliable. While the lack of caps remains a constant source of frustration, the tubes themselves have held up well. I’ve exposed them to a range of conditions, including prolonged sunlight, freezing temperatures, and various chemical solutions used for sample preservation.

The tubes have shown no signs of degradation or leaching, maintaining their structural integrity and chemical inertness. Cleaning is relatively straightforward, as the smooth polypropylene surface resists staining and is easily rinsed with water or mild detergents. Compared to my previous experience with cheaper plastic tubes, which often became brittle and discolored after repeated use, the Corning Falcon tubes have demonstrated superior long-term durability.

However, the ongoing cap issue continues to overshadow the tubes’ positive attributes. Having to purchase separate caps or rely on makeshift closures defeats the purpose of using disposable tubes for contamination control. While the Corning Falcon tubes outperform cheaper alternatives in terms of durability and chemical resistance, the added expense and inconvenience of sourcing caps independently diminishes their overall value proposition.
